Abstract
The utility model relates to a simple and reliable bearing nut which comprises a riveted thin-wall section, a tightening section connected with the riveted thin-wall section and a sealing section connected with the tightening section. When the bearing nut is used for tightening the bearing, the riveting thin-wall section of the nut is impacted by the riveting gun to enable the riveting thin-wall section to be deformed and riveted on the rear axle tube, so that the nut can be prevented from loosening after being impacted, meanwhile, an oil seal is arranged on the sealing section of the nut, namely a sealing journal of the oil seal, therefore, other parts of the rear axle body do not need to be provided with the sealing journal, the rear axle structure is more compact, and the number and weight of rear axle parts are reduced.
Description
Technical Field
The utility model relates to the field of multifunctional tightening piece structures, in particular to a simple and reliable bearing nut.
Background
In use, the rear axle hub bearing is typically secured with a larger bearing nut which only serves as a preload. In order to ensure reliable use of the bearing, an anti-loosening mechanism is usually additionally arranged to prevent the bearing nut from loosening under the impact state, and an auxiliary oil seal is also required to be installed to prevent bearing failure caused by unbalanced lubrication conditions of the bearing due to grease loss in the bearing, so that more parts are required to be equipped for the bearing nut, the overall weight of the rear axle is increased, and two installation procedures are also increased.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provides a simple and reliable bearing nut.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
a simple and reliable bearing nut comprises a riveted thin-wall section, a tightening section connected with the riveted thin-wall section and a sealing section connected with the tightening section.
Further, the cross section of the tightening section is in the shape of a regular polygon.
Further, the outer circumferential surface of the seal segment is a circumferential surface.
Further, the thin-wall section, the tightening section and the sealing section are riveted into a whole.
Further, the diameter of the sealing section is larger than the diameter of the tightening section.
When the bearing nut is used for tightening the bearing, the riveting thin-wall section of the nut is impacted by the riveting gun to enable the riveting thin-wall section to be deformed and riveted on the rear axle tube, so that the nut can be prevented from loosening after being impacted, meanwhile, an oil seal is arranged on the sealing section of the nut, namely a sealing journal of the oil seal, therefore, other parts of the rear axle body do not need to be provided with the sealing journal, the rear axle structure is more compact, and the number and weight of rear axle parts are reduced.
The beneficial effects of the utility model are as follows: by adopting the bearing nut with the locking and sealing functions, the faults of looseness and the like caused by impact of the nut are prevented without additionally arranging a locking mechanism, and oil seal sealing journals are not required to be additionally arranged on other parts; the variety of rear axle spare part can be reduced, rear axle weight has been reduced.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a schematic side view of the present utility model.
Description of the embodiments
As shown in fig. 1 and 2, a simple and reliable bearing nut comprises a riveted thin-wall section 1, a tightening section 2 connected with the riveted thin-wall section 1 and a sealing section 3 connected with the tightening section 2.
The section of the tightening section 2 is polygonal, the outer peripheral surface of the sealing section 3 is a circular surface, the riveting thin-wall section 1, the tightening section 2 and the sealing section 3 are integrally formed, and the diameter of the sealing section 3 is larger than that of the tightening section 2.
When the bearing nut is used for tightening the bearing, the riveting thin-wall section 1 of the nut is impacted by a riveting gun to enable the riveting thin-wall section 1 to be deformed and riveted on a rear axle tube, so that looseness caused by impact of the nut can be prevented, meanwhile, an oil seal is arranged on the sealing section 3 of the nut, namely a sealing journal of the oil seal, therefore, other parts of a rear axle body do not need to be provided with the sealing journal, the rear axle structure is more compact, and the number and weight of rear axle parts are reduced.
By adopting the bearing nut with the locking and sealing functions, the faults of looseness and the like caused by impact of the nut are prevented without additionally arranging a locking mechanism, and oil seal sealing journals are not required to be additionally arranged on other parts; the variety of rear axle spare part can be reduced, rear axle weight has been reduced.
The foregoing is only illustrative of the present utility model and is not to be construed as limiting the scope of the utility model, and all equivalent shapes or structural changes made by the present utility model/description and drawings, or direct or indirect application in other related technical fields are included in the scope of the present utility model.
